AIR DEFLECTOB.

Application filed July 28,

To alt wlw/m. 'it may concern Be it known that l, JoHN E. KNAPP, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Air Deiectors, and de- Clare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this speciication.

My invention relates to improvements in air deflectors for mo-tor vehicles adapted to be releasably secured to the wind-shield standard.

The object of my improvements is to provide an air delector capable of being swung to any desired position, the glass so pivoted that one side thereof will swing freely' through the span of the supporting arm lthrough an are ot' over 300 degrees. Such delector is also provided with means for being secured at any position to which it may be swung and comprises a frame itseltl adapted to be swung to any desired position, such frame being also capable ot'adjustment of its span to receive panes of glass ot varying sizes, and provided with gripping members adapted to grip the pane ot glass on opposite edges without any alteration in the glass to fit the gripping member, such gripping members being Secured to the frame in a manner which permits of their being easily and quickly manipulated so that the glass may swing to any desired position and retain such position except against the application of an external force.

ln the drawings,--

Figure l is a view showing my device attached to a wind-shield standard.

Fig. 2 is an elevation of the device, the wind-shield standard being broken away.

Fig. 3 is a detail drawing showing construction of the supporting frame.

Fig. 4 is a detail section of the pivot connection of the gripping members with the supporting frame.

Fig. 5 is an end view of the gripping member. I

Fig. 6 is a diagrammatical view showing adjustable positions.

Fig. 7 is a modification in plan.

Fig. 8 is a modification in section on the line 8 8, Fig. 7.

Let a: and a? indicate' opposite halves or 1920. Serial No. 399,494.

sections of a pivotally mounted supporting arm within the span of which is pivoted a pane of glass g. This supporting arm is adapted to be adjustably pivotally mounted on the wind-shield standard b, by means of a clip c. This clip is adapted to be releasably secured to the wind-shield standard by means of bolts or screws 02 as shown in Figs. 2 and 6. The clip carries the supporting arm as shown in Figs. 2 and 6, screws c3 being provided to hold this supporting arm in any position to which it may be adjusted in the clip. lit will be seen by loosening the screws c3 the supporting arm may be rotated about its longitudinal axis to any position within an arc limited only by the windshield, and the screws then tightened so as to secure it in such adjusted position.

These separate halves or sections of the supporting arm indicated as a. and a2, are adjustable relative each other increasing or diminishing the span so as to receive the glass g which may be supplied in varying sizes. Section t ot' the arm is provided with f a sleeve e secured thereto, such sleeve adapted to receive for longitudinal adjustment therein section a? oi' the arm. Section a2 carries a radial pin (Z which runs in slot d2 in thesleeve e. Sleeve e is tapered at its upper extremity, as shown in Fig. 3 at e2, and threaded at such end below the tapered portion to receive a thumb-nut f. rThis thumbnut is likewise tapered, but to a greater extent than the taper on the sleeve so that when the nut is screwed down on the sleeve it will compress the same against the arm a2 so as to hold such arm firmly therein at the point to which it may have been adjusted.

A pane of glass g is held in place so as to pivot within the span of the arm by means of pivotally mounted gripping hngers 7L. rThis pane ot glass will be permitted a movement thru an arc of over 300 de- 1 grecs, one side swinging freely within the radius of the span. lhese gripping iingers are grooved as at. il? to receivethe glass g, and a rubber packing or packing of other similar material, as' indicated at i, is provided to protect the glass from the metal of the gripping fingers. Adjusting nuts j are threaded into the gripping fingers on opposite sides of the groove h2 so that when the nuts are adjusted inwardly against the side of the rubber packing it will be retained firmly in place.

These gripping ingers are pivoted for rotation within the arm, as shown in Fig. fl,

I, by means of a tapered shank h3 adapted to I erted to rotate such shank.

A modification is shown in Figs. T and 8 in which a st-raight shank is provided and the inner face of the arm is provided with radial grooves m extending from the open ing thru the arm, which grooves are adapt-- ed to receive a fixed pin n, carried by the shank of the gripping finger, a spring 0 being used to hold the ground end of the gripping inger outwardly against the arm.

1t will be observed that the supporting arm itself may be rotated to any position desired about its longitudinal axis and secured in such position; that longitudinal adjustment of the sections of the supporting arm is permitted so as to increase or diminish the span in order that panes of glass of varying size may be used and further that the glass is so supported within the span of the arm as to permit free rotation thru an arc of over 30() degrees, or until limited by the wind-shield itself; also that the pivot connection between the glass and the arm is of such a character that the glass will be retained at any angle to which it may be rotated in its adjustment.

What l claim is:

, l. In a side shield air deflector for motor vehicle windshields, in combination with the windshield supporting standard, a supporting arm adapted to be releasably, adjustably, pivotally mounted upon said standard to be carried thereby, said arm comprising a pair of relatively longitudinally adjustable sections turned over at their outer extremities about a pane of glass supported therebetween, one of said sections provided at its inner extremity with a longitudinally slotted sleeve serving as an extension thereof and which sleeve is of such a size as to receive said other section of the pair, which other section carries a lug adapt-- ed to travel in the slot in said sleeve, said sleeve tapered at the outer end and provided with a tapered nut screw-threaded thereon to bind said sleeve closely about the inserted supporting arm section, and rotatably adjustable and releasable gripping fingers carried at the outer extremities of said supporting arm adapted to engage the opposite ends ofa pane of glass swung from the span of said arm, and a pane of glass engaged by said gripping fingers.

2. In a side wing shield air delector for motor vehicles, in combination with the windshield supporting standard, a supporting arm pivotally mounted upon said standard for adjustment at varying'positions rotatable and longitudinally thereof, said arm comprising two sections turned over at their outer extremities about opposite ends of a pane of glass swung therebetween, said sections capable of relative longitudinal adjustment to engage panes of glass of varying size, a removable glass pane swung within the span of said arm, opposed gripping {ingers, one carried at each extremity of the supporting arm and each comprising a gripping port-ion adapted to engage the pane of glass, and a tapered shank portion extending through a tapered aperture in the arm and provided with an adjusting nut, and spring means adapted to hold said tapered shank yieldingly to its seat in the arm.

In testimony whereof, I sign this specilication.

JOHN E. KNAPP.
